[英]Reverse engineering: How to generate SOAP Request XML in the backend?
我有以下課程:
WS接口:
package com.mypackage;
import javax.ejb.Remote;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
@Remote
@SOAPBinding(style = Style.DOCUMENT)
@WebService(name = "MathService", targetNamespace = "http://mypackage.com/")
public interface MathServiceWS {
@WebResult(name = "result", targetNamespace = "http://mypackage.com/")
@RequestWrapper(localName = "addRequest", className = "AddRequest", targetNamespace = "http://mypackage.com/")
@WebMethod(action = "http://mypackage.com/add", operationName = "add")
@ResponseWrapper(localName = "addResponse", className = "AddResponse", targetNamespace = "http://mypackage.com/")
Long add(@WebParam(name = "add", targetNamespace = "http://mypackage.com/") AddBean add);
}
WS實施:
package com.mypackage;
import javax.ejb.Stateless;
import javax.jws.WebService;
@Stateless(mappedName = "MathService")
@WebService(serviceName = "MathService", endpointInterface = "com.mypackage.MathServiceWS", portName = "MathServicePort", targetNamespace = "http://mypackage.com/")
public class MathService implements MathServiceWS {
@Override
public Long add(AddBean add) {
Long first = new Long(add.getFirst().intValue());
Long second = new Long(add.getSecond().intValue());
return Long.valueOf(Math.addExact(first.longValue(), second.longValue()));
}
}
豆子:
package com.mypackage;
import java.io.Serializable;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(
name = "Add",
namespace = "http://mypackage.com/",
propOrder = {
"first",
"second"
}
)
public class AddBean implements Serializable {
private static final long serialVersionUID = -7727938355039425419L;
@XmlElement(required = true)
private Integer first;
@XmlElement(required = true)
private Integer second;
public AddBean() {
}
public Integer getFirst() {
return first;
}
public void setFirst(Integer first) {
this.first = first;
}
public Integer getSecond() {
return second;
}
public void setSecond(Integer second) {
this.second = second;
}
}
在部署此WS之后,當我在SoapUI中添加WSDL時,在給出用戶輸入后,add方法請求如下:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:myp="http://mypackage.com/">
<soapenv:Header/>
<soapenv:Body>
<myp:addRequest>
<myp:add>
<first>1</first>
<second>2</second>
</myp:add>
</myp:addRequest>
</soapenv:Body>
</soapenv:Envelope>
現在,我希望在com.mypackage.MathService.add(AddBean)
方法中使用給定的用戶輸入獲得上述SOAP請求XML。
com.mypackage.AddBean
上使用JAXB只生成部分請求 任何指針都會非常有用。
您可以創建自定義SOAPHandler對象,並可以讀取請求有效內容並通過自定義屬性將其設置為SOAPMessageContext。 確保將范圍設置為應用程序。
在服務類中,使用@javax.annotation.Resource
注入javax.xml.ws.WebServiceContext
並通過自定義屬性訪問有效負載集。
例如:
1.創建處理程序並注冊它。
public class PopulateSOAPMessagePayloadHandler implements SOAPHandler<SOAPMessageContext> {
public static final String SOAP_MESSAGE_PAYLOAD = "__soap_message_payload";
@Override
public boolean handleMessage(SOAPMessageContext smc) {
Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
if (!outboundProperty.booleanValue()) {
// for incoming:
ByteArrayOutputStream bout = new ByteArrayOutputStream(1024);
try {
smc.getMessage().writeTo(bout);
String payload = bout.toString(StandardCharsets.UTF_8.name());
smc.put(SOAP_MESSAGE_PAYLOAD, payload); //Set payload
smc.setScope(SOAP_MESSAGE_PAYLOAD, MessageContext.Scope.APPLICATION); //make it application scope
} catch (SOAPException | IOException e) {
e.printStackTrace();
// handle exception if needed
throw new WebServiceException(e);
}
}
return true;
}
// Other method (no-op) omitted
}
2.獲取有效負載
public class MathService implements MathServiceWS {
@Resource
private WebServiceContext context;
@Override
public Long add(AddBean add) {
String payload = (String) context.getMessageContext().get(SOAP_MESSAGE_PAYLOAD);
Long first = new Long(add.getFirst().intValue());
Long second = new Long(add.getSecond().intValue());
return Long.valueOf(Math.addExact(first.longValue(), second.longValue()));
}
}
希望能幫助到你。
您可以輕松完全控制文檔。 首先讓我們設置bean:
@XmlRootElement(name="addRequest")
@XmlAccessorType(XmlAccessType.FIELD) //Probably you don't need this line. it is by default field accessible.
public class AddBean implements Serializable {
private static final long serialVersionUID = -7727938355039425419L;
@XmlElement(name="first",required = true) //you don't need name attribute as field is already exactly the same as soap element
private Integer first;
@XmlElement(name="second",required = true) //you don't need name attribute as field is already exactly the same as soap element
private Integer second;
public AddBean() { }
//Getters and Setters
}
現在,我認為這是你正在尋找的部分。 添加自定義命名空間聲明和設置前綴等。如果使用org.springframework.ws.client.core.support.WebServiceGatewaySupport.getWebServiceTemplate
發出SOAP請求,則可以執行以下操作:
public class WSCastorClient extends WebServiceGatewaySupport {
public CustomResponseObject callWebService(Addbean add) {
WebServiceTemplate wst = getWebServiceTemplate();
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.afterPropertiesSet();
wst.setMarshaller(marshaller);
wst.setUnmarshaller(marshaller);
wst.afterPropertiesSet();
CustomResponseObject response = (CustomResponseObject)
wst.marshallSendAndReceive(add, new
WebServiceMessageCallback() {
public void doWithMessage(WebServiceMessage message) {
SaajSoapMessage saajSoapMessage = (SaajSoapMessage) message;
SOAPMesage soapMEssage = saajSoapMessage.getSaajMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
SOAPEnvelope soapEnvelope = soapPart.getEnvelope();
SOAPHeader head = soapMessage.getSOAPHeader();
SOAPBody soapBody = soapMessage.getSOAPBody();
//Now you have full control of the soap header, body, envelope. You can add any namespace declaration, prefix, add header element, etc. You can add remove whatever you want.
soapEnvelope.removeNamespaceDeclaration(soapEnvelope.getPrefix()); //clear whatever namespace is there
soapEnvelope.addNamespaceDeclaration("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
soapEnvelope.addNamespaceDeclaration("myp", "http://mypackage.com/");
soapEnvelope.setPrefix("soapenv");
soapHeader.setPrefix("soapenv");
soapBody.setPrefix("soapenv");
Document doc = saajSoapMessage.getDocument();
StringWriter sw = new StringWriter();
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.transform(new DOMSource(doc), new StreamResult(sw));
}
});
return response;
}
//close off other brackets if I forgot any.
